SA to change bushfire guidelines

South Australia will develop stricter guidelines on when bushfire seasons should start and end after an investigation into an Adelaide Hills blaze.

The Cherryville fire was sparked by a burn-off on private property in May last year, after the close of the official bushfire danger season.

It raised concerns over whether the season should have been extended or whether a total fire ban should have been declared on the day.

But Emergency Services Minister Michael O'Brien said on Thursday the investigation into the blaze had found no justification for either an extension of the fire season or the declaration of a total fire ban given the risks posed by the conditions on the day.

However, Mr O'Brien said the investigation did find the processes used to determine when fire seasons should start and finish in various districts were inconsistent across the state.

"The committee has tendered advice to government that this process be improved by using a stringent and documented system of assessment," the minister told state parliament.

Mr O'Brien said this was likely to include greater consideration of the weather outlook and consultation with private landowners.
